How to Configure the DS54 for one-button turnout controlThe local buttons, throttle, or any other turnout control device connected to the LocoNet can control the DS54 output when the DS54 is connected to the rails. The following drawings indicate the general wiring schematic for a one-button control of a turnout using either a Dual Coil (upper) or slow motion (lower) switch machine. The following two charts indicate operating criteria and CV settings for one-button turnout control.

Can the output of the DS44 power more than one slow motion switch machine such as a Tortoise at the same time? No, the DS44 was designed to only drive one slow motion switch machine on each of its four outputs. Connecting more than one switch machine is not advised and could burn out the DS44.

Q: Is it possible to use Digitrax equipment to wire the Kato N-Scale Automatic Track Crossing? If so, how do I do it? A: The answer is a probable "No", but there may be a workaround. The Kato, USA website notes: Some Unitrack components such as the Automatic Crossing Gate and 3-Color Signal were designed with DC operation only. So, the official position is that that these devices don't work in the DCC environment. However, we are not above speculating on how to do this, nor are others. An online web search turned up this bit of message traffic by ...

In this example we add some more features to complete the capabilities of the DS64 / BD4 combination. In addition to the fascia button, we utilize the remaining sensors of the BD4 to automatically select the exit route if triggered by the advancing train. For this purpose, each yard track will need a short detection section just before the yard ladder. A departing train will then trigger and set its own exit route as soon as the engine enters the detection section. To enter the yard however, the routes must still be selected manually with the push buttons.

You can automate grade crossing signal lights with block occupancy sensors. Install a BD4 to detect track occupancy as shown in the figure below. Other than removing the Op Sw35 commands from the routes used in the related article example, there is no additional programming needed for the DS64. Sensor operated occupancy detection requires that all rolling stock be equipped with resistor wheels for proper detection or that the detection section is longer on each side of the RR Crossing than the full length of a train since only the locomotive will draw current. A lighted caboose on the end of ...

This example is a small yard with a crossing signal at its entrance. We will use independent turnout addresses to demonstrate the flexibility that the DS64 offers. Here, route (track) 2 3 and 4 will activate the blinking light when set and the deactivation is done by resetting to route 1, the main line. The advantage of this setup is that you can easily do operating RR Crossing lights without the need for additional equipment for block detection. The turnout output utilized for the RR crossing operation is simply integrated into the route setup. In addition to the route ...

Simple Example of a Yard Ladder with Manual Route Buttons in a hidden yard. Set DS64 OptionSwitches 11 and 15 to 'c' closed to enable route commands from local inputs. Make sure the momentary-on push buttons are wired as shown in Fig.1 above. OPSw 11 enables the local inputs to trigger the routes stored in the DS64. A1 will trigger route1, S1 will trigger route 2, and so forth. OPSw 15 prevents the local inputs from directly triggering the outputs.Option Switch Configuration Press the OPS button on the powered DS64 for about three seconds until the red led begins ...

A cascaded route is where the last command of a route triggers the next route; this is also known to some as a nesting route. With the capacity of 8 turnouts per route, it becomes necessary to cascade routes if more than 8 turnouts are involved in a route. To highlight these possibilities, we use a very complex scenario with many turnouts and possible routes. Cascading routes allows the setup of long routes without the need for a computer. Since some routes exceed the capacity of 8 turnouts, the remaining turnouts of the long routes are setup in the second ...

Can the DS52 be powered directly from a 13.8 v DC external power supply instead of the rails? No. Screw Terminals 4 & 5 are used to not only supply power to the DS52 from the track but also are the path that is used to both program the DS52 and to operate the DS52 via a throttle or computer program.

Q: Can I set up the DS54 for two-button operation turnout control? A: Two-button control (one button for setting the points to the main route and the other button for setting the points to the diverging route) is a standard configuration for the control of any turnout. The following charts indicate operating criteria and CV settings.

Q: What is the procedure for programming the DS54 Address using the Programming Address Button? A: The procedure for programming the DS54 address using the Address Programming Button is simple. This procedure only requires the determination of the turnout addresses block for the DS54. During the programming cycle the activation of any turnout address within the desired turnout address block will automatically set the DS54 to the proper module address.

This procedure is best done after installation of the decoder to the turnout. The process is "blind", so it is easier to program this decoder after installation because you can then test the operation of the turnout with its new address. The DS51K1 can be installed into the base of the turnout or attached to the bottom of the layout near the turnout.1. Turn off track power and temporarily connect the yellow programming wire from the DS51K1 to the same rail as the black wire.2. Turn on track power.3. Using your throttle, select the address you want to program into ...

The DS51K1 is designed specifically for Kato N-Scale turnouts. Kato manufactures both a #4 and #6 turnout; one DS51K1 will control one Kato turnout solenoid. In cases where there are two turnouts in a crossover track arrangement, you must use two DS51K1s, each assigned to the same address.Installation of the four decoder wires requires soldering skills. And, just to make things interesting, Kato uses the colors of black and red for their turnout control wires, while Digitrax uses black and red for the power and data bus. You will make four connections, two connected to the turnout motor and two ...

For some reason it is not possible to successfully operate Fulgurex point motors with a DS64. Tortoise work fine. We have determined that the Fulgurex motor draws too much current for the DS64. Published sources describe the Fulgurex motor as needing 400 Ma for operation, which is well beyond the capacity of the DS64. When the DS64 tries to operate Fulgurex motor, the excess current draw appears to be a short circuit and the DS64 shuts down to protect itself. The Tortoise, while also a slow motion point motor, is "on" all the time since it is a stall-type motor. ...

In addition to controlling turnouts via LocoNet with your DT400 throttle or with a computer program such as Railroad & Co., you can use local push buttons to operate turnouts. These buttons can be mounted near a particular turnout on the layout fascia or on a local track diagram. In this way, train crews can operate a turnout with a push of the button. The momentary push buttons are connected to the DS64 inputs marked S1, S2, S3 and S4. The return connection of each push button is made to "+COM. Here, a momentary button is connected to operate Turnout ...

I have my Kato Switches hooked up to a standard switch panel with toggle momentary switches. Can I hook up the DS51K1 stationary decoder in addition to this wiring? In other words, if hooked up the DS51K1 to the Kato Switch Machine that was already wired to another source to throw the switch, would the momentary power damage the decoder when it is operated by the standard control panel? I would like to operate these switches via DCC and by the control panel. In this situation, it would appear that using a DS64 configured for Kato turnouts (solenoid turnouts) and ...

The DS64 is a powerful stationary decoder. If you have tried to program this stationary decoder and are having problems, there are several things that you can do before contacting Tech Support for further help. Is the DS64 receiving enough power? The DS64 can be powered in several different ways. Although it is possible to power the DS64 from track power, this has been a source of problems for many operators due to low voltage. This typically arises on a railroad that is using power in excess of the capacities of its power supplies. Have you programmed all four addresses ...

Changing the value of a DS54 Configuration Variable with a DT400 is easy if you follow the steps listed below. 1) Disconnect the DS54 from the LocoNet, aux power source, all inputs and all outputs. 2) Short the pins of the Enable Link. 3) Connect the DS54 track terminal inputs to the isolated programming track.4) Connect the yellow (feedback) wire from any DS54 Output (A, B, C or D) to either rail of the isolated programming track. 5) DT400 Programming Steps: 6) Remove the yellow feedback wire connecting the output connector to the isolated programming track.7) Remove the wires ...

How To Run a Route with DS64:1. Select the Switch Address that corresponds to the Top Address of the route you want to run.2. Issue a Closed or Thrown command depending on which you set up in the route table.Note that if you are using an actual switch address as your top address and you send the opposite closed or thrown command from that set up in the route; you will operate that switch address only and not the route.For example: If you set up Switch Address 50 as your Top Address by sending a Thrown command, you’ll need to ...

How To Set Up Routes Using Your DS64NOTE: During this procedure the DS64 must be connected to an active LocoNet with an active command station.1. Press and hold down the STAT button on your DS64 until the green LED begins to blink quickly. You are now ready to set up a Route.2. To program the DS64 Route Number, use your DCC throttle in Switch mode to select a Switch Address from 1 through 8 and issue a Closed or Thrown command. This lets the DS64 know which of the 8 available routes you are setting up. This is NOT the ...

When you program the DS64, you must program all four outputs, even if they are not connected to anything. A "Virtual" top address can be used to avoid conflicts with actual turnout addresses and other routes. To create a virtual top address use a switch address for your top address that is not used to operate an actual turnout on the layout. The advantage of this is that you can consistently use either the "thrown" or “closed” command to operate all routes, making it easier to remember which position goes with which route to make them work. Since DS64 routes ...

Can a DS64 be powered from the LocoNet RailSync lines? No. The LocoNet cable is used only for LocoNet commands. The DS64 must be powered via the rear modular connector (12-14 volts AC or DC) OR via the AUX power 12-16 volts DC using AX1(-) and AX2(+) on the circuit board at the front of the unit. It is also possible for the DS64 to get it's power from the track hooked to Trk A and Trk B terminals, but experience has proven that this power source may not be reliable in certain situations. NOTE: Use only the rear power jack or ...

Q: How can the DS54 be configured to control a Flashing Crossing Signal? A: The elements necessary to create a simple function flashing/blinking crossing signal are: a block occupancy detection (trigger) device, an electronic flashing/blinking circuit (DS54) and a crossing signal. The DS54 can accommodate two different types of triggering devices: Digitrax block occupancy devices (BD1 and BD4) and third party block occupancy devices (such as magnets and reed contacts). The following drawings indicate how to connect the two different types of triggering devices, along with the crossing signal, to the DS54. The upper drawing is for the BD1 or ...

On the DS64’s control panel, press and hold the ID button ...

Hook up for slow motion type turnout machines & crossing gates.Note: Multiple turnout machines of the same type can be operated on a single DS64 output.For example, you can run 2 Tortoise or Switchmaster machines on a single DS64 output.Note: If you find that your turnout is operating “backwards” simply switch the + & - wire connections to achieve correct operation.Note: The outputs can be configured to drive a grade crossing signal. See Knowledge Base article.

Can I mix solenoid & slow motion turnout motors on a single DS64?No.The DS64 is configured for either for solenoid turnouts (the default setting) OR slow motion turnouts. Only one type of turnout motor can be used on any particular DS64.If you have both slow motion and solenoid controlled turnouts on your railroad, different DS64s must be used for each type of turnout.

Once you have set up the DS64 to operate the type of turnouts you will use, the next step is to hook up the turnouts to the outputs of the DS64. Each type of turnout machine has specific requirements for wiring.Note: The DS64 is configured for either for solenoid turnouts (the default setting) OR slow motion turnouts. Only one type of turnout motor can be used on any particular DS64.Note: Multiple turnout machines can be operated on a single DS64 output.For example, you can run 2 Peco or Atlas Snap Switches on a single DS64 output. Up to 4 Kato ...

At the factory, your DS64 was set to control solenoid type turnout machines that use a single pulse output for operation. If you are using solenoid type turnouts, you can install the DS64 “out of the box.” If you have reconfigured your DS64 for stall motor type turnouts, the DS64 can be reconfigured back to solenoid type turnout motors.1. Connect the DS64’s ‘TRKA’ and ‘TRKB’ terminals to your track. No turnouts should be connected to the DS64 at this time.2. On the DS64 press and hold the OPS button down for about 3 seconds until the red OPS LED and ...

At the factory, your DS64 was set to control solenoid type turnout machines that use a single pulse output for operation.

Q: What is the purpose of the single 6-32 screw terminal beside the input connector? A: The 6-32 screw terminal next to the input connector is the -VE Sensor common for the BD1 and BD4 block occupancy detectors. The 6-32 screw terminal next to the input connector should not be mistaken for the standard system ground. The LocoNet connector handles all of the DS54’s system ground needs. Warning: Do Not Connect the 6-32 screw terminal to a house or earth ground (water pipe, electrical ground connection, earth ground stake, etc.) as it may result in damage to the DS54.

Q: Can I assume that any of the 3 powering options for the DS64 are acceptable for OpSw changes? A: Yes you can power the DS64 using any of the 3 options. The DS64 is strictly looking for power, and doesn't need the DCC signal from the track to set op-switches. Q: If I have only 3 turnouts on a DS64, to complete the 4 point programming I have been inputting a bogus turnout number. Is that correct? A: Yes, that is correct. Q: When setting OpSw 1, do I have to be connected to track power or can I power ...

Automated Routing with DS64 Routes are a way of operating a preset combination of turnouts to predefined positions using a single Switch command. Route tables hold the Switch Address and position information that make up the Route that operates when a single command is issued. The DCS100 Super Chief can store up to 32 individual routes that consist of a "Top" address and 7 additional turnout addresses and their positions. The DS64 has a route table that can hold up to 8 individual routes that consist of a "Top" address and 7 additional turnout addresses and their positions. Sensors ...

Q: How do you connect more than one DS64 to a single power supply like a PS14 to power them or do you need a separate power supply for each DS64? A: One power supply can be used if it can provide adequate power for all the DS64s it is powering. The PS14 has a built-in circuit breaker; when it exceeds its capacity, it will shut down, cool off and then start up again. If you are experiencing this behavior then you need to add one or more PS14s to provide enought power for the DS64s you have connected. Our recommendation of one ...

I'm looking to wire Tortoise switch machines on a DS64. When the track switch is thrown I want to power 1 color light (non-LED). When the track switch is closed, power a different colored light. Is this possible using the DS64 inputs or the Tortoise connections? The DS64 does not have separate connections for indicator lights for trackside or for a control panel. However, indicator lights can still wired to work with the DS64. Tortoise or other slow motion swith machines can be wired in two different ways. If using LEDs, a two leg, bipolar LED can be connected in ...

Can the DS51K1 be used with large scale DCC (22 volts)? What is the maximum DCC supply voltage for this decoder? The DS51K1 is designed specifically to be used with Kato N-Scale Unitrack turnouts only. It will not work for large scale turnouts. For use with bi-polar turnouts in large scale, the DS64 is a better choice.

Q: I am building a new DCC layout that will include a logging spur that is simply a single long piece of track with no loop. I want to have a train go back and forth on this track which automatically reverses when it gets to each end. While the AR1 was designed for reversing loops, can it be wired to simply reverse a train on a straight piece of track? A: Not in the way that you intend. One of the interesting problems with DCC is that we often still think in terms of DC, where the track polarity ...

Q: What is the purpose of the Program Enable Link? A: The CV Program Enable Link is used to program the DS54. The link (two pins) must be in the open position (one pin uncovered) for normal DS54 operation. The link (two pins) must be in the closed position (both pins shorted by the shorting block) during the programming of the DS54. Warning: The DS54 will behave erratically if the link is closed during normal operation.

There are two jumpers on the DS52 stationary decoder board. To properly use your DS52 you must be sure these jumpers are in the correct position. The configuration jumper sets whether your DS52 operates slow motion or solenoid type turnout machines. When the jumper is open it will run solenoid turnout machines. When it is closed it will operate slow motion turnout machines. The programming jumper determines whether the DS52 is in programming mode or not. To program the addresses for the DS52 the program jumper must be closed. For normal operation, it must be open.

Q: How can I configure the DS54 for block occupancy detection? A: Any DS54 input can serve as a block occupancy message generator. All that is necessary is to activate a DS54 input with a device that can detect the presence of a train within a specific area/location. The DS54 input can respond to a number of different block occupancy devices including the BD1, BD4, and isolated contacts. The following drawings indicate two different methods (wiring schematics) for the connection of devices to the DS54. The upper drawing Is for isolated contacts and the lower drawing is for BD1 ...

When using a DCS100 or DCS200 to setup routes within the Command Station in conjunction with DS64 Stationary Decoders, the DS64 needs to be connected to Track Power. The DCS100/200 does not send internal route messages via LocoNet. DCS100/200s only send Routes as a series of switch commands out to the Track in DCC format. The DSC100/200 were designed in 1996 and had no requirement to echo these same switch commands out via LocoNet. Additionally, DS64 Stationary Decoders are designed to allow up to 8 Routes to be programmed internally into them. Please refer to the DS64 manual and other ...

Q: How do I reset the DS54 CV's to factory default values? A: The DS54's CVs must be manually reconfigured to set the DS54 to factory default values. The factory default values for the DS54's CVs are: CV01 = 1All other programmable CVs = 0

Q: Can I set up the DS54 to act as an emergnecy stop device? A: Any unused DS54 input can be configured to send an Emergency (OPC_IDLE) Stop packet. The typical Emergency Stop circuit is a supervised series of one, or more, normally closed switches or contacts. When any one of these devices is opened the circuit is deactivated and everything affected by the Emergency Stop circuit immediately shuts down. The following drawing depicts a typical Emergency Stop circuit using a DS54.

The DS54 is a powerful stationary decoder, which can be used to control devices in several different ways. Within the DS54 electronics are four independent sections. Within each section are three independent elements: Switch_, Aux_ and Output_. Each element can act independently or in conjunction with one or more elements within that independent section. (Note: The Switch_ element can be accessed from the input connector and the Output connector of the respective section.) Each of these elements can perform any one of several different actions. The actions are determined by two variables: trigger and task. The relationship of the Trigger ...

I am trying to wire my new layout (N gauge) using the DS 64 with Peco switch machine PL10. The PL10 has four wires to be attached. My question is: Do I need to attach all four wires or just one set of wires? The PL-10 is a coil-type switch machine with double solenoids. One solenoid is activated to make the track switch throw in one direction, and the other is activated to throw it in the other direction. All four connections are required, with one for each solenoid being common and the other two being for the individual coils. ...

Can I use the DS64 to power frogs in Atlas turnouts with solenoid ( code 83 ) type switch machines? No, the DS64 does not have internal contacts to provide power to the frogs. This could be done by using a switch machine with its own contacts; these have been made by NJ International, Tenshodo, PFM and others. Another alternative would be to use the Atlas Snap Relay. The Snap Relay is a solenoid device like the switch machine, but instead of throwing the turnout, it throws a set of electrical contacts. The relay is wired in parallel to the switch machine, ...

Setting up DS54 for Standard Turnout Reporting The creation of a feedback circuit for standard turnout reporting is simple. Connect a normally open set of contracts attached to the switch machine, a normally open set of contacts of a micro switch monitoring the turnout throw arm, or the normally open contacts of a relay monitoring the switch machine to the common (green) and switch (red) wires to the desired DS54 output circuit. The following two diagrams indicated the two most common switch machine configurations plus the contact configuration for turnout reporting. Note: The location and type of contacts available for ...

I was wondering if I could use an output on the DS64 to momentarily apply power to a Kadee #309 electric uncoupler? OpSw 02, 03, 04, &05 closed would give me a 3 second pulse. The Kadee uncoupler may require as much as 3 Amps @ 22 Volts. So, what is the current carrying capacity of the outputs on the DX64 [sic] ? What is the maximum DC voltage I can apply to terminals AX1 and AX2? The DS64 can accept 12-16 volts AC or DC on the rear modular jack or 12-16 volts DC on the AX1 (-) / ...

Why does the DS64 generate multiple output pulses for a single command? I get between 2 and 5 pulses over a period of about 2 seconds. Option Switch 01 determines the type of turnouts that you can operate, static or pulse. The Factory default is for "Pulse". Option Switches 02, 03, 04, and 05 set the pulse length. OpSw 02 = Closed the pulse width is 200ms (milliseconds). OpSw 03 = Closed, the pulse width is 400ms. OpSw 04 = Closed, the pulse width is 800ms. OpSw 05 = Closed, the pulse width is 1600ms. All, or any combination of ...

Q: I am setting up a yard control panel with a CML Electronics DTM30. For the DTM30 to know what state a turnout is in, it can issue an interrogate command but my DS54's do not seem to respond with this information. Is there a trick to this? A: According to CML: The DTM30 makes use of the “Interrogate” feature that all modern Digitrax systems use. After power up, the Command station normally sends out 8 switch commands. All accessory devices respond to these, and send LocoNet messages back reporting sensor states and point states. The DTM30 can also send ...
